Embodiment Construction

[0012] Such as figure 1 As shown, the present invention is composed of a six-degree-of-freedom motion platform 1 and a large hydraulic cylinder 2 in series. The hydraulic cylinder 2 is at the bottom, and the top supports a six-degree-of-freedom motion platform 1. There is a fixed experimental cabin.

[0013] The six-degree-of-freedom motion platform 1 is composed of a base 3, a hydraulic cylinder 4, a universal joint 5, and an installation platform 6. The six hydraulic cylinders 4 are fixed on the plane of the base 3 and the top installation platform 6 through the universal joints 5 at both ends. Two hydraulic cylinders 4 are adjacently formed into a group, fixed on the base 3 in a V shape, and every two groups are installed in a W shape on the mounting platform 6 on the top, that is, any four adjacent hydraulic cylinders 4 are W-shaped or M-shaped.

[0014] When the sea state to be simulated is given, the computer gives a motion trajectory of the installation platform 6 acco...

Abstract

The ship motion simulator as one integral electromechanical apparatus consists of a six-freedom motion platform and large hydraulic cylinder connected serially, and the experiment cabin is fixed to the top of the six-freedom motion platform supported by the large hydraulic cylinder. The present invention can simulate the motion of ship in sea based on the requirement of experiment. The two-stages composite motion simulator of the present invention has great motion range for simulating ship motion state of ship in 1-6 scale of sea state. After one sea state scale, say 6 scale, in the range is given, the control system will give the motion locus of ship in the said sea state, 6 scale of sea state and the simulating platform will move in the given locus under the drive of the hydraulically driven simulating platform.

Description

technical field [0001] The invention relates to a simulation device, in particular to a ship motion simulation device. mechatronics [0002] technology field. Background technique [0003] Ship simulators are not only used in various amusement places to allow passengers to experience the wind and waves at sea, but also more widely used in ship operation training, boat adaptation training, seasickness mechanism and preventive drug research. When a real ship sails at sea, different tonnages and different structural designs have different motion conditions under different sea conditions. In general, ship motion can be decomposed into Heaving, Rolling, Pitching, Yawing, Surging and Swaying. [0004] After literature search, it was found that Chinese patent application number: 93202162.X, name: a six-axis motion simulator, which uses automatic control means to make the working platform obtain three different orientations and speeds and various pitches, swings, and rolls The r...
